We live here Where weather occurs. Ozone depletion is the term commonly used to describe the thinning of the ozone layer in the stratosphere. In general, air pressure and density decrease with altitude in the atmosphere. Consequently, unabsorbed and dangerous ultraviolet radiation is able to reach the Earth's surface at a higher intensity. Scientists, who specialize in the measurement of the ozone layer, use the Dobson unit, which is 0.01mm thick at the Standard Temperature and Pressure (STP). The ozone layer protects life on Earth from harmful solar ultraviolet (UV) radiation. The temperatures in the stratosphere are inverse to those in the troposphere, meaning they rise with altitude. Each layer has its own properties, depending on how far you are from the surface of the planet. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. After the stratosphere, you move into the … Region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. The United Nations General Assembly has designated September 16 as the International Day for the Preservation of the Ozone Layer. , The breakdown of ozone in the stratosphere results in reduced absorption of ultraviolet radiation. above troposphere, contains ozone layer, the layer of the atmosphere that lies between the troposphere and the mesosphere and in which temperature increases as altitude increases; contains the ozone layer The atmosphere is made up of five total layers, varying in... See full answer below. It is the layer in which we live. An ‘Ozone Hole’ would approximate to an area where the ozone concentration drops to an average of around 100 Dobson Units. Its structure means that If we start from the top of the troposphere and go further into the sky, we reach the layer known as the stratosphere. Although the concentration of the ozone in the ozone layer is very small, it is vitally important to life because it absorbs biologically harmful ultraviolet (UV) radiation coming from the sun.

The air here is extremely thin, and the conditions here are more similar to the ones we find when we leave the Earth’s atmosphere entirely. The Earth’s atmosphere is split into many different layers of gas. Between 1928 and 1958, Dobson established a worldwide network of ozone monitoring stations, which continue to operate to this day. The ozone layer is destroyed over time by products that contain chlorofluorocarbons. The Stratosphere: Ozone's Home . Higher still is the thin air of the mesosphere, where meteors burn up. This molecule plays an important role acting … It contains the ozone layer, which is the part of Earth's atmosphere that contains relatively high concentrations of that gas. Anderson, S. O., Sarma, M. K., and Taddonio, K. (2007).  These in turn are being replaced by hydrofluorocarbons (HFCs) and other compounds that do not destroy stratospheric ozone at all.  A gradual trend toward "healing" was reported in 2016.. The higher we go in this layer of the atmosphere, the ‘’thinner’’ the air gets, meaning it is significantly harder for us humans to breathe. Because the general pattern of the temperature/altitude profile, or lapse rate, is constant and measurable by means of instrumented balloon soundings, the temperature behavior provides a useful metric to distinguish atmospheric layers. Ozone layer, also called ozonosphere, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3 ). The ozone layer protects life on Earth from harmful solar ultraviolet (UV) radiation. These replacement compounds are more reactive and less likely to survive long enough in the atmosphere to reach the stratosphere where they could affect the ozone layer. This tracer helps scientists study ocean circulation by tracing biological, physical and chemical pathways . The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically.. Temperatures in the stratosphere are highest over the summer pole, and lowest over the winter pole.By absorbing dangerous UV radiation, the ozone in the stratosphere protects us from skin cancer and other health damage. Xu, Y., Zaelke, D., Velders, G. This organohalogen compound is able to dissolve into the ocean's surface waters and is able to act as a time-dependent tracer. All life on this planet is affected by the changes that happen in this layer, as all the weather changes take place in the troposphere. The air in this layer is absolutely not friendly for us, as it would be impossible to breathe in the mesosphere because of too low oxygen levels. Also, this layer of the atmosphere has the lowest temperature of all layers, and they drop down to -90° C. The layer that is located between 500 and 1000 km above the Earth’s level is known as the thermosphere. The first layer from the earth surface is the troposphere. But if you want to understand what ozone's all about, you need to understand that it can be good, and it can be bad. The magnetosphere also contains the Van Allen radiation belts, where highly energized protons and electrons travel back and forth between the poles of Earth’s magnetic field.
